Caliper crack mark



FIG. 1 is a front elevation view of a caliper crack mark according to my new design with the left, right and rear elevation views being a mirror image of;

FIG. 2 is a cross-section view thereof taken along the line 2-2 of FIG. 1;

FIG. 3 is a bottom perspective view thereof; and,

FIG. 4 is a bottom plan view thereof.

The stippled shading in the Figures shows surface contouring and does not represent surface ornamentation.

The broken lines in the drawings illustrate portions of the caliper crack mark and form no part of the claimed design. The dot-dash-dot broken lines in the drawings define the bounds of the claim and form no part thereof. 

CLAIM I claim the ornamental design for a caliper crack mark, as shown and described.
